The short answer for these models
When the AC family will not cool, the fault is usually in the path the cold air takes rather than in the machine that makes it. This family is one model number, which makes the scope of this page unusually clear. Work the path from the door inwards and the expensive cause is the one you reach last, not first.
The observations that separate this fault from its neighbours
- The unit never cycles off — A compressor that runs without a break is a compressor that never reaches its cut-out point. Continuous running is the same fault seen from the control side.
- The cabinet sides or the back are noticeably hot to the touch — Rejected heat has to go somewhere. Hot panels with a warm interior usually mean the heat is not getting away from the condenser.
- The cabinet recovers overnight and drifts warm during the day — A machine that is only just coping. It points at heat rejection or at how often the door is opened rather than at a failed part.
- NEAR MISS — the cabinet is silent and nothing is cold — Silence changes the question entirely: that is a no-power, start-device or control fault, and it belongs on a different page.
What to suspect, in order, on this family
- Blocked airflow from a frosted evaporator — Ranked first because on cabinets of this build the evaporator sits directly in the air path, so ice there stops cooling the cabinet before it stops the machine. Nothing else on this list produces a warm cabinet with a unit that is plainly working.
- A stopped or obstructed evaporator fan — Second, and it looks identical from the outside. The fan is the part that moves cold out of the evaporator compartment, and on these cabinets it is the item most likely to be stopped by ice rather than by its own failure — clear the ice and the fan question answers itself.
- Door seal and door alignment — Third. A seal that has taken a set lets a slow stream of room air in, which loads the evaporator with moisture and feeds the ice at the top of this list. On this family it is a contributing cause more often than a standalone one.
- Condenser airflow and placement — Fourth. Heat that cannot leave the condenser comes back into the cabinet as reduced capacity. It matters on every refrigerator, but on this line it is the cause that most often turns a marginal machine into a warm one during a hot spell.
- A sealed-system fault — Last. It is the expensive answer and the least likely one, so it should be reached by elimination and never assumed from the symptom alone.
What to check first, and why that order
- Establish which part of the cabinet is warm — A whole-cabinet failure and a one-compartment failure have almost nothing in common, and this question separates them in seconds.
- Clear the vents and repack the shelves — Done first because on these cabinets loading blocks distribution more often than any component fails.
- Leave it a full day and measure again — Cabinets of this size need hours to recover, so an immediate re-check after any change tells you nothing.
- Check the fan and the condenser last — Both need a panel off or the cabinet pulled out, so they sit at the end of the owner-side sequence.
Before you open anything
Safety
Power off at the breaker or the plug before any cover comes off, and treat the compressor area as live until it is. Leave the door switch wired as it is: it cuts power to the internal fan for a reason, and defeating it puts a moving blade in reach of a hand. Anything on the sealed system is licensed work; do not open refrigerant tubing. While the cabinet is warm, treat the food by the clock rather than by the look of it: a refrigerator holds food safely at 40 °F (4 °C) or below and a freezer at 0 °F (−18 °C) or below. Above those, move anything perishable to a cooler with ice and keep the door shut.

When to call a technician
The line on these models sits where the tools change. Adjusting a seal, clearing vents and cleaning a condenser need nothing a household does not have; testing a fan motor, a defrost heater or a control board needs a meter and the cabinet open, and refrigerant work needs a licence. Call sooner rather than later if the cabinet is above safe temperature, because food loss usually costs more than the diagnosis.
